[Prior art] Multi-layer optical film 'that is,' a glue that provides at least part of the desired light transmission and / or reflection properties through micros of different refractive indices. These multi-screen optical films are manufactured by depositing a series of inorganic thin layers (microlayers K ', miCrolayers,) on a substrate. Generally, the substrate is a relatively thick glass sheet, and due to the limitation of the true volume and / or the deposition method on the degree of uniformity that can be achieved ', :: is limited. ψ Recently, it has been demonstrated that multilayer optical films can be made by coextrusion of alternating polymer layers. Please refer to U.S. Patent Nos. 3,61 (), 724 (named RGg, 4,4 paper land (Rogers et al.), 4,540,623 (Im et al.), 5,448 surgery et al.), And 5,882,774 (J〇 nza et al.). In these polymeric film towels, polymer layers are mainly or wholly used to form individual layers. These films can be made by high-capacity manufacturing methods and can be made into large pieces and whole rolls. However, the application of ° σ production requires a relatively small number of films. One such application is the calender used in various photodiode detectors. Fiber optic windows and reflectors and / or photon filters for photonic elements are used for additional applications. For these applications, small multi-layer optical films can be cut from large films of this type using mechanical components, such as cutting devices (such as scissors), or cut with a blade. However, the force exerted by the cutting mechanism on the film 85255 200404674 can cause delamination in areas along the film's cutting line or edge. This is especially true for many polymeric multilayer optical films. The delamination area can often be seen by the difference in color from the entire area of the film. Because multilayer optical films rely on the close contact of the layers to produce the desired reflection / light transmission characteristics, the delamination region does not provide these desired characteristics. In some product applications, delamination may not be a problem or even worth noting. In other applications, especially where the film is essentially reflective throughout the entire film from the beginning to the end, or where the film will be subject to mechanical stress and / Or when the temperature changes widely ^ one layer will be very unfavorable. Therefore, there is still a need for an improved method of subdividing multilayer optical films and objects containing such films. This method preferably does not cause delamination on the cutting line or the film edge, cuts the film cleanly without accumulation of large debris on the film, and can be used in conjunction with automatic and / or continuous manufacturing methods. [Summary of the Invention] The present application reveals that the method of subdividing or cutting a multilayer optical film body including a multilayer optical film to a film is divided into one or more independent small pieces in an early case. The multilayer optical film body It is basically composed of multiple layers of light 睪, π, and 骖. In this case, the multilayer optical film body may also include a pseudocrystalline layer, which is suitably one or more additional layers of the multilayer optical film. The first and second linings are transferred to the opposite main surface of the multi-residence film body. Bund I ^, Man. Car 乂 佺 passes laser radiation through one of the linings (arbitrarily designated as the first lining) to the multiplicative y, ^ 卞 I plate body, the laser radiation is suitable to generate a cutting line to define The first backing sheet and the rubber 0 & 2 I Nanu 2 small and many small pieces. Laser shots usually produce plume smoke and debris ^ Average, children accumulate on the work piece-in this case 495 85255 200404674, tied to the-lining. After that, the first and second moons of the first month are removed from the multi-layer light τ, μ, l, and the sheet body W, H with debris) 'while the multilayer optical rubber lining is supported by the second lining. The removal can be accomplished by contacting the first optical film body with a tape and pulling the tape apart. At least the first lining of the car is made of Li Di ^ & electric method ^ added to the film body. After forming the cutting line with the field shot wheel and before the first lining: W /, before removal, the neutralizer 7 (neutralize 7) can be used to reduce the electrostatic attraction between the first and the multi-layer optical film body. Although laser_ is a better technique for cutting film bodies, in some cases "alternative methods such as rotary die cutting and ultrasonic cutting are also used. [Embodiment] :. As used herein, "" Glue Matter "" refers to an extended optical body with a thickness of ~ • 丨 ,,,, or the center of a rain blade, or "Mill 丨, s)). In some cases,-a film can be attached Affixed or applied to another optical body, such as a hard substrate or another film with proper reflection and transparency. The film can also be in a physically flexible form, regardless of whether it is self-supporting or attached to other optical films. On the flex layer. The term "film body", as used herein, shall mean a film, itself or in combination with other components, such as in a laminated film construction. FIG. 1 depicts a green-multilayer optical film body 20. The film body includes individual microlayers 22 and 24 °. The microlayers have different refractive index characteristics, and some light is reflected at the interface of the adjacent two layers P. The microlayers are quite thin, so reflections at the multi-screen interface can be constructive or destructive to give the film the desired reflection or light transmission properties. For an optical film designed to reflect ultraviolet, visible, or near-infrared wavelengths 438 85255 200404674, 'Light of Light', each microlayer generally has an optical thickness (ie, physical thickness times refractive index) of less than about 1 micron. However, it may also include a relatively f-layer 'such as a skin layer on the outer surface of the film, or a protective boundary layer disposed in the film to separate the 7 microlayers. The multilayer optical film body 20 may also include one or more thick adhesive layers for bonding two or more multilayer optical films into a laminated sheet. The reflection and light transmission properties of the evening optical film body 20 are a function of the refractive index of the individual microlayers. Each microlayer can be characterized by the same plane (ίη · ρΐ 叫 2, emissivity, and refractive index ηζ related to the film thickness axis) at least in part on the film. The birefringence index represents the subject material pair along each other. The refractive index of orthogonal, broad, and ζ ::: vibrating light (see Figure υ. In fact, the 'refractive index' is controlled by careful material selection and processing conditions. The film body 20 can usually be composed of dozens or hundreds of layers. Two alternating polymers A, B are co-extruded, followed by multiple layers as needed: the output is passed through-or multiple multiplication dies, and then the extrudate is stretched or oriented to form the final film The obtained film is usually composed of tens or hundreds of individual microlayers, and the thickness and refraction ratio of the microlayers are specially designed to be in the desired spectral region such as visible spectrum or near red line. In order to achieve a high reflectivity with a reasonable number of layers, the adjacent microlayers are included along the X_ stop values. ^ ㈦. # The refractive index difference (Δηχ) of the glaze polarized light is preferably at least ... High reflectivity, the refractive index difference of polarized light along the y-axis of adjacent microlayers (△ ) Is preferably at least 0.05. Otherwise, the refractive index difference energy can be ≧ 0.05 and preferably about 0 to produce normal reflection-polarized light and normal incident light that passes through orthogonal polarization. Multi-layer stack. The right refractive index of the light polarized along the z-axis (Δηζ) between neighbouring and thinking, A € can also be specially set ri + μ port in the P-polarized component of the incident light Reaching the desired anti-49 / 85255 200404674 point, the following explanation is easy: 'Any correlation on the interference film will be' tolerated as oriented in the plane of the film 'so that the value of Δηχ2 is taken again. Therefore, △ ~ The value of Δηχ can be equal to or less than (but not greater than) Δηχ. Which material layer 2 is selected when quoting the refractive index difference △ ~, Any, △ ~ is subject to △ Er being a non-negative number. In other words, To form a boundary in the middle of the coast ~ is "η〗" ", where j = x, y or 2 and its 遽 付 遽 卜 2 is selected by the price βη, that is, △ ~. To maintain the oblique angle ρ · High reflectivity of polarized light, refractive index mismatch between microlayers ~ can be controlled to be substantially small The difference in emissivity Δηχ makes the refraction 15 < more preferably 25. A ζ-value of zero or near zero will cause the reflectivity of its ρ-polarized light between the microlayers to be different. The incident angle is a function of constant or close to The interface of the constant ^. Furthermore, the ζ-refractive index can be controlled to refraction with the same plane, that is, this case is the same: the comparison of the two poles with opposite polarities, ㈢, the reflectivity of P_polarized The interface that increases with the angle of incidence, as in the case of S-polarized light. Representative bulletin W99 / 36248 (Neavin et al.) That can be used to make polymerized multilayer optical films. ) /, At least one of the materials should be a polymer with a large absolute value of the pre-drying coefficient of the heart. 1 It is better to produce a large birefringence material when stretched. 乂 七 GAN sΛ 1 乂 is 0.05, more preferably at least about oi or Even 0.2). Depending on the application of the multi-layer film, the refractive index may be between two orthogonal directions in the plane of the film, one or more fakes-the direction of the seven-person gate and the direction perpendicular to ^ ^, or a combination of the two. Occasionally. When the isotropic refractive index of the unstretched polymer layer is very different, it can be magnified.

And WO 99/39224 (〇uderkirk et al.) . Polymeric multilayer optical films and film bodies may include additional layers and coatings selected for their optical, mechanical, and / or chemical properties. See U.S. Patent No. 6,368,699 (Gilbert et al.). Polymeric films and film bodies may also include a helmet layer, such as a metal or metal oxide coating or layer. In a simple specific example, the microlayer may have a thickness equivalent to that of a 4/4 wave stack, that is, configured as an optical repeating unit or a cell, and each unit is substantially equal to an equivalent optical thickness (f-ratio = 50%). Composed of two adjacent layers, these optical repeating units can be effectively reflected by constructive interference light having a wavelength twice the total optical thickness of the optical repeating unit. These configurations are shown in Figure 丨 where the microlayer 22 of polymer A and the microlayer 24 of polymer b are adjacent to form a cell or optical repeating unit 26 'which is repeated throughout the stack. A thickness gradient along the film's thickness axis (eg, z-axis) can be used to provide an enlarged reflection band. A chaotic design that makes these 85255 200404674 sharp edges with a thickness gradient can also be used, as discussed in US Patent No. 6,1,57,490 (Wheatley et al.). Other layer configurations, such as multi-layer optical films with 2 microlayer optical repeat units with a 50% difference in factory ratio, or films with optical repeat units consisting essentially of more than 2 microlayers are also included. These alternative optical repeat units reduce or eliminate certain higher-order reflections. Please refer to US Patent No. 5,360,65. (ArendSfA ^ 5, 103,337 ^ b (Schrenk #,). Figure 2 shows a front view of a part of a multilayer optical film body 30. The film body 30 The angular dimension is larger than the size required for special end use manufacturing and sales. Therefore, it is necessary to subdivide the film body 30 into smaller pieces to make the film suitable for the purpose. The size and shape of the desired small piece can vary widely. For brevity, see figure 2. Figure 2 shows the parallel cutting lines from the second intersection and group, labeled as π and% of the jinjie 疋. If both sets of cutting lines are used, the film body 30 is transformed: 1, in two directions, win The length and width of the sheet body 30 are independent squares) or parallelograms. If only-sets of cutting lines are used,: Small = into elongated rectangular bars. Of course, the cutting line does not have to be straight, the regular ... / line and any combination of straight line segments are required. Or other polygonal openings = early shapes such as circles, rectangles, parallelograms, etc. Applicants have found that laser radiation can be optical film, and τ Α d and subdivided and aggregated multiple layers ^ Do not cause any fancy in the cutting line厗 M ^ is selected to have a $ +, 彳 仃 Beibei delamination. The wavelength of the laser radiation material combined at this wavelength, at least some of the optical film will be shaken, and the absorbed light will evaporate. Otherwise, + Han Tian will make the film body cut along the film, and the incident light will be transmitted or reflected by the film like other incident light with a wavelength in the film's predetermined operating range 85255 -13- 200404674. Laser radiation is also formed into a certain shape with appropriate focusing optics and controlled to a suitable power level to complete evaporation along a narrow cut line. Laser radiation is better. It can also quickly scan through the work piece according to the pre-programmed instructions, and quickly open and close. It can follow any shape of the cutting line. A commercially available system for this aspect is being sold under the LaserSharp brand laser processing module sold by Dagger Industries (St. Paul, MN). These modules use a CO2 laser source and operate at a wavelength of about 10.6 microns (from about 9. ^ 1 = microns) to cut the work piece. · "Applicants and others have also found that 'laser radiation cutting materials will accumulate on the work piece as debris. These residues will accumulate to the extent that the film is not acceptable for the intended use. To avoid This is the problem. Before the radiation cutting operation, the first optical-thin film is applied to the multilayer optical film body. If close contact is maintained between the multilayer optical film body and the cut: any debris generated by the first = will accumulate on the first substrate. On the film rather than on the mind: on the pubic film body. However, the first lining is also preferably applied in a conducive: pre-emptive way, but I have #lacquer, yttrium easy to remove earlier, and then I do it The multi-layered optical film body small piece 21 liner can be applied to the 4: private film body with static electricity before laser cutting. The electrostatic charge can learn the attraction of the film body at least in part later, so it can be allowed They are separated. Or-sheet-to-adhesive: low-layer adhesive, such as re-adhesive office note 2: a kind of "laser radiation is better to pass through the first piece when cutting. Therefore" unless Uncoated optical glue-liner at wavelength The film 'otherwise the same small 85255 -14-200404674 film on the nn shell' is because the two layers are kept in close contact. That is, it is controlled to cut the small pieces of the multilayer optical film body, so the second " " The linings are cut to be essentially the same ... 乂! It will also expose the paper to two shots, the younger brother of the car —-lining series paper. The adjacent multi-layered optical film body is bonded to two small pieces of the following layers, but still retains the desired properties. This paper is reasonable-the surface is better to receive light: a ^ ^ ^ ώ / _ / day 710yo. Film Other materials with minimum or non-rotation during exposure, field, and shooting can also be used. = For convenience of transportation, a multilayer optical error film opposite to the first lining can be applied: a second lining is applied on both sides And by appropriately selecting the liner to control the laser radiation, the so-called "knock-cut" can be achieved along at least some of the cutting lines, so that the first-the liner and the multilayer optical film body completely evaporate at the cutting line-but the first The two liners do not evaporate at all, but are at least partially complete, and preferably substantially complete Complete. According to this method <, the multi-layer optical film body can be divided into small pieces, but it can still be held in an orderly configuration and carried in a belt or sheet for rapid processing. The second backing sheet is used as a substrate for supporting and supporting the individual pieces after cutting. Please note that the second lining can support and support individual pieces, regardless of whether they are placed on or under these pieces. FIG. 3 illustrates an example of this aspect. In the cross-sectional view of the figure, the polymeric multilayer optical film body 40 is depicted as a single layer for simplicity. The first backing sheet 4) and the opposite main surface of the second backing sheet 44 which has been applied to the film body 40 remain in close contact. The lining 44 is shown as including two layers 44a, 44b for reasons discussed below. The radiant rays 46a, 46b, and 46c pass through the lining 42 and are respectively aligned with the cutting lines 48a, 48b, and 48c of the film body 40. Provide appropriate beam-shaping optics and power control 85255 -15-200404674 (not shown) ': the narrow gap shown is formed by evaporation of the lining 42 and the film body 40 while the lining 44 remains substantially intact. Some evaporated material will accumulate on the first lining 42 as debris 50. The cutting line and the gap define the divided pieces 40a, 40b, 40c of the multilayer optical film body 40 and the corresponding pieces 42a, 42b, 42c of the liner 42. In Fig. 3, the small piece of the liner 42 and the small piece of the multilayer optical film body 40 are kept in close contact by, for example, electrostatic attraction or other reversible attachment mechanism. The mountain cutting lines 48a-c may be formed simultaneously or successively. Above. "Using the laser processing module can scan the laser radiation of a single beam, so that the radiation 46a-c represents the sequential scanning of the beam. As mentioned above, other cutting technologies such as rotary die cutting and ultrasonic cutting can be laser radiation. An acceptable alternative method is shown in Figure 4. Figure 4 depicts a technique for the convenient removal of debris-coated liner pieces 42a-c from multi-layer optical film moon ugly pieces 40ac. Place pressure sensitive tape called a touch on the figure The structure of 3 is such that the pressure-sensitive adhesive tape is in contact with the first liner 42. If the laser cut% liner 42 is electrostatically fixed to the film body 40, the electrostatic force is preferably substantially neutralized or at least reduced so that the liner The attractive force between the sheet 42 and the film body 40 is substantially smaller than the attractive force between the lining sheet 42 and the squeaking glue T 52. Then, by just pulling the tape 52 from the film body 40 or vice versa, the lining pieces 42a-c can be quickly removed from the film body 4〇a_ \ This way, it can be easily and quickly removed Thousands and thousands of independent, consulted small pieces of lining. The adhesive tape 52 preferably extends to the width of the multilayer optical film body 40. When the door is in contact with a row of small pieces to be cut 0 42a-c, the Yuzi film body pieces 40a-c are also separated from the second liner 44 . This is preferably done on the film body :. With: Liner 85255 16 200404674 44 is provided with a relatively weak bond. Such adhesion can be achieved by static electricity or by using a small amount of low-tack pressure-sensitive adhesive. The adhesion is weak; the small pieces 40a-c can be easily separated by passing the small pieces 40a-c at the sharp corners or f-curves of the sheet 44 and gently removing the small pieces 40a-c. The second " lining 44 preferably comprises at least two layers of knives which are selected to facilitate cutting. The layer 44a disposed adjacent to the multilayer optical film body 40 is preferably composed of a material having a substantially lower absorption of lightning than the film body 40. Because of its relatively low absorption, the layer 44a can be hardly fired by properly controlling the laser during the laser cutting process. It has been found that the thickness of the polyethylene material is about ^ ⑵ micron) or more = enough for the CO2 laser cutting system under the operation of about 2 micron. Iron, this material will be stretched or deformed by the heat generated by the laser on the cutting line. The right profile 44 is kept under tension and is used to remove the multi-layer prior film body 40 through the laser cutting area. The stretching or deformation of the lining layer will cause the small piece to be said: "two move against each other and are misaligned" and thus cause Laser cutting with wrong positioning :. For this reason, the layer 44b is preferably composed of a relatively high-modulus material, such as high-mold 2 coated paper, in order to keep the size of the film body 4G and the film patch_c dimension stable. By using the laser cutting procedure, the multilayer optical film body piece _c is hardly delaminated, and by using the first and second linings 42, 44 the main surface is also clean and free of debris. The heat generated by the laser can deform the microlayer edges and create a seal like a multilayer optical film. Figure 5 shows a front view of a small piece of polymerized multilayer optical film body, which has been subdivided from the larger piece of polymerized multilayer optical film body and cut as shown in Figure 3, so that the small maggot has a defined-long strip of laser light.

The side portions 64a and 64b define the alignment holes and the long strips of women's clothing are in the injection molding device. These edges are also preferably cut with kisses: ,,, | | Straight line holes for perforation lines, so that they can be torn along these lines-or when J is cut in the field, the laser radiation is preferably controlled to The point 66 can completely cut through (not only kiss cut) the multilayer optical film body and the first and second linings. Among them, the hole preferably intersects the edge portion 62a and the other hole intersects the edge portion 62c. / D -Provided by the side-Small holes or notches for easy tearing.-The melting zone 68 is formed by reducing the laser radiation to such an extent that the multilayer film body 60 does not completely evaporate. This can be achieved by making the laser beam go Focusing, reducing the laser power and / or making the laser sweep over the work piece faster. Although some multilayer optical film bodies will evaporate in the melting zone 68, at least a part of the multilayer, > film thickness will be between The melting zone 68 remains intact, although it will be distorted by local additions. This distortion will be manifested in local ripples or overvoltages of the microlayers and / or the combined and eventual loss of distinct individual microlayers.

As shown in Fig. 5, the melting zone 68 extends across the entire width of the strip and is arranged in pairs. The parent zone defines an effective window area 67 and a mechanical separation area 69. Perforations may be provided in the mechanical separation area 69, as defined by point 66, or these perforations may be omitted. Whether the perforations are provided or not, the fused region 68 adjacent to the separation area 69 is better than -18-506 85255 404674. On, 俾 is not affected by the width of the strip. Xi Pingzhong: / The process is twisted and extends through the entire twisted, "said" film strip is adjacent to each-melting zone. This multi-layered book, which has not been bent, can be used as a buffer through the entire dividend π, using tension in the f σ region 67, or two mechanical actions (such as applying 1 "knife method if there is a perforation) to each other Helps prevent delamination and extension during separation. = The optical film body can also contain—or multiple layers of optical ㈣ # 口 并 > Its composition and thickness are selected so that such an outer layer ^, know to add a medium tension g Bu Ke Tear open.

An adhesive layer can be used to coat the multilayer optical adhesive. The multilayer optical film body thus constructed can be sandwiched in a second removable liner, and then a cutting line can be formed through a second laser. During laser cutting, the multi-layer optical film is positioned so that the tearable outer layer adjoins the second laser light. In addition, laser light can be cut at least some: control ^ only partial injury cutting (evaporation) through the wind ^ 2 3 pre-cursor film body, full hair passes through more than one child, but leaves the outer layer can be ripped to maintain complete. After the laser and after the first and second photomasks are removed, due to the complete outer layer two: a multilayer optical film body in the form of a continuous sheet, then only by hand = pulled apart along the cutting line or η ^ early machine By applying such a moderate force, it can be seen that ^ is also separated into divided pieces defined by the cutting line. Tension at the time of separation ^ 70 Wang Muzhong on the tearable outer layer. Many of the films included in this configuration rarely experience tension when separated and, in the case of clearly defined small pieces: Zhou; ^ pj 85255 19 200404674 has a sealed edge. The probability of delamination of the multilayer optical film during separation is therefore essentially zero. The cutting lines described here are indicated by the symbols 49a, 4 ^, and 49c in the figure and above. These numbers are similar to those in FIGS. 3 and 4, but the multilayer optical film body 40 is shown with a tearable outer layer. 40d is adjacent to the second lining 44. These cutting lines can replace each pair of melting areas 68 and dots "shown in Fig. 5 so that the window area 67 can be easily separated into small pieces. The four peripheral parts (see Figure 5) can also be used for these cutting lines, or if laser radiation is needed, the entire multilayer optical film body (including the tearable outer layer) can be cut at the positions shown in Figures 3 to 4. One or more multi-layer optical film body pieces 60 can be put into the molding machine using the alignment holes defined by the side portions 64a, 6b. Alas, the bright polymer material can be formed in the box or frame 114 surrounding the small piece of 6G, which is shown most clearly in the cross-sectional view of FIG. 6. After cooling ', the multilayer film body 60 can be mechanically cut along the perforation line defined by point 66 to manufacture individual calender assemblies. These individual calender assemblies and their uses are in U.S. Patent Application Serial No. 10 / 152,546, entitled "PhOTOpic Detect〇r System and Fmer. Optical device) "(applications were made on May 21, 2002). The calender frame may include an aperture adapted to receive a light detector. The combination of the photodetector / calender assembly can provide an improved detection system. The light ~ 11 lbs is partly derived from the spectral properties of the photodetector and partly transmitted from the spectrum of the multilayer optical film. . The use of the above method of subdividing a multi-layer optical film body into small pieces is not limited to forming a strip of such material for a box type calender. This method can be used to obtain small pieces of multilayer optical film bodies (especially large quantities of small pieces, for example, at least 10, at least 50, or at least 100) from larger films or rolls of such materials. 508 85255 -20- 200404674 a Q: ... especially where delamination along the edge of the multilayer optical film will become / combine and the entire multilayer optical film body must have a clean surface. : # 田 、 会 —A roll-to-roll method of 200, which is used to clean and quickly transform an optical film body into a small piece of a multilayer optical film body. The roll 202 is unwound to provide a laminated film 2 () 4, which can be basically composed of a poly film body (for example, ㈣4G in FIG. 3) and adhered to a multilayer optical adhesive :, the main surface (arbitrarily designated as the second main surface) The second lining is formed by the lining 44) in FIG. 3. In a previous step not shown, the sheet is applied by electrostatic attraction or using a small amount of low-tack adhesive; the second major surface of the optical film body. The lamination film roll idler roller 206 is passed 'to make the multilayer optical film body contact the roller 206. The laminated film 205 is then driven by a torque driving roller 208, 2120. The first sheet 212 (for example, the piece 42 in FIG. 3) is unwound from the roll 214, and is kept close to the laminated film 204 by the idler roller 216 and the film is applied to the laminate by passing the conventional electrostatic rod 218 Multi-layer optical film body assembly of the false film 204. The electrostatic force applied by the electrostatic rod 28 may cause close contact between the first lining 2U and the first major surface of the multilayer optical film. The cymbal combination 204/212 ("Original Tape" (web)) then passes through the laser radiation station 220, where the laser light from the laser control module 222 is aimed at the original tape to produce a multilayer optical film Body and the first small piece of lining 224, as shown in Figure 3. Provided-platform 226, which has a honeycomb arrangement hole connected to a vacuum source 228 to keep the original tape across its entire width (the original tape (Horizontal) and a considerable portion along its length (downward direction of the original belt) are flat. Laser module 222 includes beam shaping and steering optics and controllers, each of which can cut warp programs under predetermined power settings Designed cutting line pattern, at the same time Ηβ9 85255 -21-200404674 The original belt moves at a constant speed. Or, _ / one, cutting the first cutting, w〆, and Nisshou original belt in each shot group 222 can stop moving, bran succession Green a, emperor ..., silly, ..., k, do n’t stop again to let the group cut the second cutting line pattern, and then follow the j-stop-repeated pattern. The laser radiation station 22〇 preferably includes- The exhaust hood 23G 'is made to provide a strong air flow through the original belt in the 疋 direction. Air flow Helps reduce the optical distortion caused by the plume of smoke and debris generated by the laser = point. The beam turning in the cutting field 222 is better to turn the laser cutting point on the original belt to be essentially forceless. Move in a direction parallel to the direction of the air flow to further avoid distortion caused by plume smoke and debris. After the original belt leaves the laser radiation station 220, the 'now part is cut into small pieces 224' immediately near the conventional neutralizer rod The neutralizer lever can eliminate or at least reduce the electrostatic attractive force between the small piece of the multilayer optical film body of the layer 4 and the small piece of the first liner 212. After the adhesion between the corresponding pieces is so weakened, the tape 234 That is, the self-winding roll 236 is unwound and passed through a pair of milk, ⑶, and one side of the adhesive tape 234 coated with an adhesive is pressed on the discontinuous piece 224a of the first liner. A reeling roller 238 places the adhesive tape 234 on— When it is opened in the other direction and the other take-up roller 240 is used to open the original tape in the other direction, the tape door 4 is separated and the first piece of small lining 224a coated with debris is now a pure piece 224b of the multilayer optical film body. Take away. Then, take the original coated stone嗣 之 ρΕτ 概 片 μ Loosely wound 'is temporarily protected during storage and handling. In a later step, the second backing sheet can be guided to a sharp bend or radius to fix the loosely fixed multilayer optical film body piece 224b from The second lining is completely separated. The rollers 233 and 235 can be driven at a fixed speed to serve as the speed circle of the roll-to-roll system 2000. Depending on the number, density, and square of the cutting lines to be manufactured by the laser module 222 85255 -22- 200404674及 和 种 / 疋 'original' (that is, 'film Honghe ⑽a 12') will be greatly weakened at laser station 220. To prevent the original belt from breaking, it may be necessary to leave the original belt to a long strip, And preferably, each side of the original tape has a long strip, shell and uncut 'to provide additional strength of the original tape. Such a continuous strip ′ is referred to herein as “weed” and can be discarded immediately after rolling 233, 235, as shown by number 244. FIG. 8 shows a top view of the original tape 250 including a polymeric multilayer optical film body sandwiched between the first and second linings at a laser light station 22 (see FIG. 7). The original belt 250 moves in the direction 252. An air flow is established by the exhaust hood 23 to provide an air flow in a direction 254 across the original belt. The original tape 25Q is separated into a central working part 250a and a scrap edge part 250b, which are separated from the working part 250a by a cutting line 256. If the cutting line 256 is a cut-through thread, the original tape can be partially reinforced ', but if the cutting line is a kiss-cut line, additional reinforcement can be achieved, because in this case the lining 44 will be in the working part 25〇a and waste The edge part is guaranteed between 25 flutters = complete. The extra cut line, preferably the kiss cut line, defines representative shapes 258, 260 to be cut into small pieces. In order to help reduce the distortion caused by plume smoke and evaporated materials, the laser module 222 can be programmed to scan the laser cutting points in the preferred directions as shown in 258a, 260a_b, these directions are not parallel to the air flow direction 254 Or have non-parallel component forces. As the case may be, the original tape 250 may have two different scrap edge portions on each side, that is, the left outer scrap edge portion along the left side of FIG. 8 and the right outer scrap edge portion along the right side of FIG. 8. The extra cuts made by the laser module 222 can separate these outer waste edge portions from the waste edge portion 250b, which can be described as the inner waste edge portion and then will use a kiss cutting line at 256. If it exists, the outer waste edge part can be separated from the inner -23-51 2 85255 200404674 waste edge part and collected immediately after the laser cutting station 22G. These scrap edges can help provide a clean, flat edge for the final roll. The same-day scrap edge part and the rest of the original tape—the same goes through the roll 233 > 235 ° as described above. Example of making a polymeric multilayer interference film 'will be made from 90/10 polyethylene naphthalate (PEN) / poly Low-melting black made of ethylene terephthalate (PET) copolymer: Alternating layers of coPEN and polymethylmethacrylate (pMMA) are coextruded at about 277 to form 224 individual layers Clamped by low melting point. . The extrudate in the middle of the outer cortex is composed of Qing. These layers define an optical package, which is basically composed of 112 cells and has a thickness gradient of a large straight line along the axis perpendicular to the stack. The thickest unit on one side of the bag is about 3 times thicker than the thinnest unit on the other side of the bag. The optical bag is asymmetrically multiplied to obtain a multilayer optical film structure having 448 individual layers and two outer skin layers and an inner polymer boundary layer (PBL) in the middle of the bag. The layer doubling is performed in such a way that-the total thickness of the optical package is about i · 3 times that of the other package. The extrudate was quenched on a chill roll to form a cast multilayer film. The cast film is stretched sequentially in the machine direction (MD) and the machine direction (TD) using stretching ratios of 3 4: 1 and 3.4: 1, respectively, to obtain a finished film, which is in the same plane as the copen layer. The refractive index (ηΐχ, η &) and the non-coplanar refractive index (nlz) are about 1.744, 1.72, and L50, respectively, and the coplanar refractive index (n2x, n2y) and non-coplanar refraction in the PMMA layer are respectively. The rates are about 1.495, 1.495, and 1.495, respectively. All refractive indices were measured at 550 nm using a MetricOn surface ripple feature device. The finished film contains two optical packages, each of which is a 1 / 4-wave design, and each has a thickness gradient of approximately a straight line S12 85255 -24- 200404674 along the axis perpendicular to the film plane to obtain a certain range in each optical package Reflection wavelength. The thickness of the thickest cell of the finished film is about 1.8 times the thinnest of the finished film, which corresponds to a reflection wavelength range of about 665 nm to 1220 nm. The outer skin layer of the optical structure is a low melting point copEN with a thickness of about 11 microns (0.43 mils). The total film thickness was about 90 microns (3.7 mils). According to the optical properties of the two special rolls, two rolls of film made substantially the same were selected and corona treated to improve the adhesion. One of the corona treated films was coated with about 122 micrometers (5 mils) with UV-induced adhesive and irradiated with UV light to start the hardening process of the adhesive. The adhesive manufactured by the hot-melt extrusion method is a thermoplastic component (ethylene vinyl acetate), a hardenable resin component (mixture of epoxy resin and polyol), and a photoinitiator component (triaryl hexafluoro Antimonate). Then, two multilayer films are laminated together and hot-dipped at 25 ° C (8 (TF) for 10 minutes to accelerate the curing of the laminated adhesive. The resulting film system is composed of two multilayer optical films and a transparent adhesive in the middle. The element is in the form of a roll with a thickness of about 12.4 mils (300 microns), a width of about 4 inches (100 mm), and a length of at least about 50 feet (from more than 10 meters). The film body or interference element has a reflection band in the near-infrared wavelength region and a transmission band in the visible region for normal incident light. The transmission percentage is about 70% at about 450-640 nm, and less than 1% at about 700_1140nm. And less than 5% at 680-700 nm and 1140-1160 nm. The second liner is a high modulus paper with a thin layer of polyethylene adhered to it with a strong pressure-sensitive adhesive. The thickness of the paper is about 2 dense (50 microns), the thickness of the polyethylene is about 1 mil (25 microns) and the total thickness of the second lining is about 3 (85255 -25-microns).

(戋 者; one of the multilayer optical film laminated in the Λ method The main surface is that the vinyl layer can be used in contact with the multilayer optical film body (bread / adhesive adhesive and use the same procedure.) This is rolled up and stored for several nanometers: ―The liner is a high modulus paper 'thickness is about 2 mils (50 microns), and one side of the soil. The paper is constructed from Litin Paper Co., Ltd., Minnesota. The components are processed in a manner substantially as depicted in Figure 7 to produce products. Mouth, many of the bars described in Sgt. Figure 5, but provide more cutting lines and melting zones 乂 8 effective windows 67 instead of 4 and as described below. The bars are about 4.5mm wide and It is about 69mm long, the length is opposite to the downward direction of the original belt, and the dazzling fusion zone is horizontal to the original belt. (Alternatively, the long strip can be horizontal to the original belt.) The melting zone adjacent to the perforation line is separated by about 5 mm, and The melting area adjacent to the window area is separated by about 5.5mm. The silicone of the paper liner (the first liner 212) is The surface is in contact with the laminated film 204. A fixed original tape speed of about 2 to 3 feet / minute (^^ ... ^^ m / s) is used. The original tape passes within about half an inch (10 mm) of the electrostatic rod 218 'The electrostatic rod system is controlled at a set value just below the arc point. The original belt also passes the neutralizer rod 232 within a similar distance. At the laser radiation station 22 o'clock, a LaserSharp laser processing module, LPM3⑼ type is used .C02 laser light spot size is about 8 mils (0.2 mm), and the width of the kiss cut and cut line produced by this is about 13-14 mils (0.35 mm). The following settings are used in The following types of cutting lines: 85255 -26- 200404674 cutting line / characteristic process speed Tang frequency kiss cut (CW) Π 〇 mm / sec 20 kHz kiss cut (DW) 8 7 5 mm / sec 20 kHz punch cut (CW) 950 mm / sec 2.2 kHz cut-through (DW) 600 mm / sec 20 kHz melting zone (CW) 1 800 0 m / sec 20 kHz In this table, cw is a cutting line that extends in the transverse direction of the original belt, and " ο ', refers to the cutting line extending in the downward direction of the original belt. In addition, for each feature, the power is set to 100%, and the task cycle Set at 50% and jump speed at 5 mm / sec. Use CW kiss cut to cut the secondary side of the bar, Gamma (see Figure 5), and use DW kiss cut to cut the main side of the bar. 62a, and circular edge portions 64a, 64b, use CW perforation to set at perforation%, use Dw to cut through the cutting line that separates the working part and the waste edge part (see line 256 in Fig. 8), and use CW to melt The zone is set at the melting zone 68. The melting zone sets the resulting melting zone, in which the upper multilayer optical film (ie, the multilayer optical film adjacent to the first liner) is completely evaporated with the first liner, and the lower multilayer optical film (adjacent to the first liner) The two-layered multilayer optical film) remains intact, but its constituent layers have considerable deformation and undulation. The continuous tape on either side of the original tape is used as the waste edge, as shown in Figure 8, but as described above, each side of the working part forms an inner and outer waste edge portion, and each inner waste edge has 4 injuries. The degree is about one-eighth of an inch (about 3 meters). This can be compared to the central working portion of the original belt (see Figure 8 again), which has a width of about 3-35 inches (about 75 to 90¾ meters). The outer waste edge is approximately half an inch wide (approximately 10 mm). The outer waste edge is separated and collected from the rest of the original belt between the laser radiation station 22 and the neutralizer rod 232. In the original strip of the laser radiation station 22 °, continuously make 85255 -27- 200404674—roll a single-sided tape with a width approximately equal to the central working part of the original tape as $ τ 2 3 4 °. Carpenter masking tape. The inner waste edge part is separated from the second backing sheet after the sketches 233 and 235, and is rolled onto the roller 23 δ together with the adhesive tape and the small piece of the first viewing sheet. Individual pieces (stripes) of the multilayer optical film body can be easily removed from the second liner by hand. During the inspection, these small films showed almost no delamination along the edge of Tian Sheqian. Smaller pieces can be obtained by applying a moderate amount of tension by hand to break along the perforation line. Examination of the edge thus cut revealed that there was a delamination at the edge 'but the delamination did not extend to the entire melting zone 68. heat. 9 It will be apparent to those skilled in the art that various modifications and changes can be made to the present invention without departing from the scope and spirit of the invention, and should be limited to the specific examples of reliability provided herein.
